Where'd you find that rendering, its fantastic? Are there more of them for different masks?
Google image search for Noble Huna. I dont know if there are others
I did, and I found it was done by Crunchbitenuvva on Tumblr, but, while they do seem to MOC from time to time, there's no more trible-esque masks. Here's a link: http://crunchbitenuva.tumblr.com/post/117792277539/tribal-esque-huna-by-me-1-hour-sculpt-in-zbrush
The Krahkaan and the Noble Huna for looks, the Great Olisi for Power.
Noble Huna for looks, Faxon for powers.
